To all whom t may concern:

Be itfknownrthat I, CHARLES E. SHADALL,

a citizen of the UnitedStates, residing at Milwaukee, in the county ofMilwaukee and State of, Visconsin, have 'invented certain newV andusefulImprovements ink Flushing'V and Ventilating Apparatus, .of which thefollowing is a specica'tion, reference being had to the accompanyingdrawing, forming apart thereof.

',This 'invention relates A'tol apparatus forA flushing and Ventilatingwater closets, urif nals andthe like.

`The Ymain objects of the invention are t6 cornbine'v in a singlefixture, flushing and.y v y l 1 pansloi Chamber 10finto adischargeScham#v ventilating apparatus; to facilitate installa@ tionandwoperation of the apparatus and generally to simplify and improve theconstructionV andbperation '0f-devices of this class;

3 is a crosssectionon the line 3-.-'3, Fig. l."

Referring to Figs. 1 and', the apparatusv comprises av casing 1,provided 'with a removable cover 2, and containing' a flush valvechamber 8 and an aspirator chamber" il. The chamber 3 is provided with anor.

mally closedV flush valve 5, which controls` the supply of 'flushingwater'to a closet bowl 'c 6, or other fixturewith which the apparatus`is connected, This valve, which'lmay'be constructed and operate invarious ways,lis in stemv 7,' freely 'fitting' inf'a socket or guide# 8,depending 'from the cover-2, and y1s adapt- Ved wheureleased, to beelosed'and held the present case, as shown, provided with a' closed vbythe 'water pressurev against a seat V9, which is preferablyremovableand' renew'- n able. Within the valve chamberbelow the. valve seat 9 andin alinement therewith, a* cylinder or expansion chamber 10 is formed,

andthis chamber' is provided with a piston ,i Specification of ALettersPatent.

Al'self-'centering' spreader' 30,

Thespreader also serves to dislodge any dirt orforeign matter which may becaught' or col.V

'et'Yopen-ingf-and to keep said A lever 31, which may be operated byanysuitable means, such as a handle 32, is pivot- `supply pipe 33,which'leads into the ush valve chamber 3 above the valve 5, a foul air Yd'scharge pipe 34, which leads out of the aspiratorl chamber 4 intowhich the tube or conduit 21 opens at its lower end above the watersealed discharge port or opening 23,

v andtwo pipe fittings or couplings and 36,

which connect the discharge chamber 19 and the lower end of the passage22, with separate passages 37 and 38, which communicate .lwith the upper'part of the closet bowl 6,

the passage 37 leading into the flush rim 39 ofthebowl The passages 22and 38 and fz the pipe iitting or coupling 36, serve both to conductfoul air from the bowl into the aspirator chamber, and to discharge thewa-l ter'usedtooperate the aspirator into the bowl. f

1n the operation of the apparatus as thus far described., when the bowl6 or other fixture is in use, the lever handle 32 is depressed, therebyopening the valve 26, while the valve13 remains closed. Water is thusadmitted through the port 26, chamber25V and opening 24, into theupperpart of the aspirator chamber 4, lthe spreader 30 being drawnupwardly7 into the opening 24 and for-ming therewith a conical jet orspray of water in the tube or conduit 21. Foul air is thus drawn fromthe bowl 6 or other fixture through'the passage 38, pipe fitting 36 andpassage 22, and entr-'ained with the jet or` spray throughL said tube orconduit into the 1 i lower part of the chamber 4, 'as indicatedby arrowsin Fig. 1. In the lower'part of lthe chamber 4 the air separates fromthe water and is discharged through the pipej connection 34, while thew-ater is `discharged through water sealed port 23 into the llower partof the passage 22,v and {iows thence through the pipe tting36 andpassage 38 into the bowl. v The bowl or other xture is thus effectivelyventilated while it is in use. Afterward, the lever handle 32 is momennvtarily lifted, thereby closing the valve 26 and l yopening the valve13. Water is admitted from the supply connection 33 through thepassage12 into the chainberlO below the piston 11, the piston is forcedupwardly'andthe valve 'liited from its seat. Waterthen rushes from theupper part of the chamber 3 through lthe port uncovered by the valve,A

into the lower part of said chamber, thence through the passage 20,chamber 19, pipe ii'tting andy passage'l?, into theiiush riin 39, fromwhich it is discharged in a spray or iihn and flushes the bowl. K

Nat-er escaping from lthe `chamber 10 through the restricted-passage 17when the valve 13 is closed, allows the piston11 to descend and thevalve 5 to close gradually according to the adjustment of the regulatingvalve-18, by which the duration vof 'the iushing operation isdetermined. V V

The operation of the modified form of the apparatus shown in Fig. 2 issubstantially the same, except that water rom both the chambers?) and 4is discharged into the bowll or other iixture, and airis'drawntherefromk through a single connection 35. r[his form or' they apparatusis applicable to a 4bowl or other fixture of the ordinary constructionhaving a flushing connectionsuch as 37, as shown in*` Fig. 1, but whenthe discharge from the opening or 'openings from the :flush .i rim orother. connection is quite restr1cted,'a

bowl or other fixture of special design, having a separate passage orconnection 381er the discharge of water from the aspirator and thewithdrawal of foul air from the bowl or other fixture, is desirable, asshown in Fig.- 1. With a bowl or iixture of such construction, thepassage 22 separated Y from the discharge passage or chamber of inFig. 1. 1 Y

Various changes in the details of construcvsa' the flush valve by apartition 40', as shown tion and arrangement of parts may be 'made vwithout materially affecting the operation of the apparatus and vwithout'departure from the principle and scope of the invention as defined inthe following claims.
